It's not just difficulty- it's really not a good thing for anybody if you have three different sewers and four different electrical service lines running to your house. It's expensive, wasteful, a mess, and can even degrade quality of service. But a variety of app stores or payment processors functioning over a common carrier (ISP, USPS) is a good thing.
